[xsl] recursive output numbering

I need to include a number attribute in my XML output, and can't figure out
how to keep it from repeating.
The problem:
I'm using recursive templates nested 3 deep. They work like this:
For each Employee,
For each Crew that employee belongs to,
For each Project that employee works on,
Generate a previously-undetermined number of new XML elements,
each including a RowNumber attribute.
Next
Next
Next
It's easy to define a variable that is incremented by the inner loop
recursive calls, so that each generated row for an Employee/Crew/Project
combination has a sequential RowNumber. What I can't figure out is how to
make sure ALL of the generated RowNumbers are unique. Sequential would be
nice, but not required. Unique is required.
Thanks,
John
